Vibration Chambers

Vibration Chambers

• Vibration test assembly with Environmental Test Chamber is designed and manufactured as per specific requirement of the customers meeting various international standards.
• Combined chamber consists of Environmental Test Chamber, Vibration Shaker Interface Provision, HMI/PC PLC based Control System etc.,
• This electrodynamic vibration shaker chamber is designed with unique features to meet the control parameters like Temperature, Humidity (optional) and 3 Axis Vibration Controls which are specified in the specification.
• Vibration Chamber is designed and manufactured in Cantilever mono block construction with motorized precise height adjustment mechanism to vibration interface shaker. Structure of the electrodynamic vibration chamber is divided in two main sections a) Outer chamber b) Inner chamber. Outer chamber is constructed/fabricated with CRCS with electrostatic powder coating to resist all kind of weather changes. Inner chamber is constructed/ fabricated with Stainless steel 304 grade sheet metal with proper reinforcement to hold thermal stress. In between the outer and inner chamber there will be an insulation using.
• High density low conduction mineral wool insulation to avoid thermal losses.
• Vibration Chamber door will have multi-pane toughened insulated window with automatic heating control system to avoid conduction for a clear view-thro. Heavy duty adjustable door hinges are used on the left-side of the chamber and on the right of the door there will be a door-locking arrangement for easy operation of the door opening and closing. Between the inner chamber and door double layer silicon gasket is used to avoid leakage.

CHAMBER DESIGN:

• Bottom of the electrodynamic vibration chamber will have specially designed interchangeable hood with interface mechanism to couple the shaker and chamber during combined tests.
• Electrodynamic Vibration Chamber will be moved up and down vertically through friction-free guided U channel and wheel.
• Electrodynamic Vibration Chamber will be moved horizontally manually using heavy duty castor wheel with railing.
• Multi-level diagonally joined airlock silicone rubber sealing the door and chamber with conduction free isolation mounts.
• Test chamber shall have illumination lamps with pre-set cut-off timings.
• Insulated door with viewing window of size 400 x 500 / 500x 700 MM or suitable with condensation free heaters. Sensors for detection of open door and safety shut-down of chamber operation and alert message on the screen.
• xFeed-through holes: Two sizes of 75 mm diameter access ports with to connect the product during active test conditions.
• The vibration chamber shall be mounted on 4” Heavy-duty castor wheels and leveling pads ensuring easy erection & movement of the system.
• Independent compartment will be provided for Refrigeration and control system in one unit. Refrigeration system is designed with Mechanical single stage / Cascade air/water cooled refrigeration system using Hermetic/Semi hermetic compressors. Refrigeration system comprises of control accessories such as Heat exchanges, Solenoid, pressure controls, Expansion devices etc., of reputed makes.
